T0 @ZZ whom 'it may concern.'-

Be it known that I, HARRY E. WTOERNLE, a citizen of the United States, and resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in F oot Bolts; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to toot-bolts, that is, bolts which are attached to the lower ends of doors for latching the door when in closed position and adapted to be operated by the foot.

The object of my invention is to provide a bolt of this character which is simple in construction, and at the saine time eiiicient and durable, and one in which the parts and the manner of assembling same present economical advantages not possessed by those foot-bolts now on the marlret.

In the accompanying drawing, Fig. 1 is a front vertical elevation of my improved toot bolt; Fig. 2 isl a side elevation in section, showing the bolt in locking position; Fig. 3 is a like view showing the bolt not locked; Fig. 4 is an elevational view of the bolt by itself; Fig. 5 is a sectional plan view .in line 5 5, Fig. 1; Figs. 6 and 7 are details of the foot lever.

In the drawing the numeral 2 designates a suitable casing which may be formed of cold-rolled steel of proper gauge and bentI to form the cylindrical portion 3 and the flanges 4 provided with screw-holes 5, by means of which the casing is secured m place on the door.

At the upper end of the casing 2 is the opening 6 for the reception of the foottreadle 7.

rllhe bolt proper 8 is tubular in form, and is provided with the slotted opening 9 through which the foot-lever passes. Opposite the slotted opening 9 are the upper and lower apertures 10 and 11 out of line with each other, and adapted to receive the inner ends of the foot-lever 7.

The bolt 8 is also provided with the slot 12 through which one end or" the spring 13 passes to engage the inner wall of the tubii lar portion 3 of the casing, as shown 1n Fig. 2, said spring otl'ering the required resistance to the movement of the bolt within said tubular casing to retain said bolt in raised position.

The foot-lever 7 is secured in position by inserting the arms through the openings 6 and 9 of the casing and bolt until the inner ends of the arms 16 and 17 come into line with the apertures 10 vand 11, whereupon by driving said footlever inwardly the said arms will spring so that the inner endsl will pass through the apertures 10 and 11, and the nibs will engage the outer walls of the bolt proper adjacent to said apertures, thereby securely holding the foot lever in position and preventing displacement or withdrawal. The curved recesses 20a engage the edges of the apertures 10 and 11. In order to operate the bolt it is only necessary to apply the foot to the foot-lever 14, whereupon the rounded portions 18 will rock in the opening 6 which acts as the fulcrum for said lever, thereby raising the bolt until the lower end thereof is released from the keeper. The spring 13 will act to hold the bolt in raised position until it is desired to lower the bolt, whereupon by applying the foot to the cap 21, the pressure of the spring 13 is overcome and the bolt lowered into locking position.

, By my invention I provide a very simple iorm of Jfoot-bolt in which the foot-lever is not in any way pivoted but is held securely in position, so that it cannot work loose and at the same time provides a very positive action in the raising of the bolt.

What I claim is: 1. A foot-bolt comprising a casing, a bolt proper therein, a foot-lever passing through registering openings in said casing and bolt and fulcruined in said casing, said foot-lever having inwardly extending spring arms beyond said fulcrum point having oppositelj,T arranged nibs at the ends thereof, and nonaligned openings formed in said bolt to receive the inner ends of said arms, whereby said nibs engage the outer walls of said bolt.

2. A ioot-bo1t comprising a Casing', a bolt proper Within said casing, a foot-lever formed of spring metal bent to form a foot rest at the outer end, rounded fuleruin portions beyond Said foot rests engaging an opening formed in said casing, the inwardly extending arms of said lever beyond said fulcrurns having heads with nbs adapted to enter non-aligned apertures formed in said bolt', whereby when said foot-lever is 10 In testimony whereof I, the Said HARRY 15 E. VVOERNLE, have hereunto 'set my hand.

HARRY E. VOERNLE.
